Chris Brown has something to smile about -- his new gold grill. The singer flashed his new hardware while signing autographs at a New York City toy store on Tuesday, The Daily Mail reports. But have no fear if you swoon over Chris Brown's smile -- the grill appears to be temporary.

However, Brown does seem to be having fun with his new look, posting a close-up of his mouth jewelry on Twitter with the comment, "Yikes!" Meanwhile, the hip-hop artist continues to be seen at the same clubs as his ex-girlfriend Rihanna. TMZ reports that the exes spent some time together at the club Avenue, and "kept a close eye on each other" from their different booths. Brown reportedly sent her over two bottles of Ace of Spades Champagne. But back to the grills. Do you think they're still in style?
